Take a look at this video.
The Chinese know the importance of keeping children healthy, but they sure do have a very odd way of going about it. This type of compulsory physical exercise before school is effective, but would never work in Australia.
So where should we draw the line between the importance of physical exercise and fun? I would imagine the Chinese children in the movie are not having fun, but this type of exercise is ingrained in their culture.
In choosing what sort of physical activity you are trying to introduce to your child, always make sure they’re having fun. If you force a child to do physical activity that he or she doesn’t enjoy, you will condition them to dislike physical activity and this will have profound effects into their adult life.
Besides, how can you explain to a child that they have to exercise so that in 20 years time they remain healthy? Always make exercise and activity fun, and the rest will work itself out.
